Effect of pollution is first marked on 

  1. Micro-organisms

  2. Green vegetation of an area

  3. Food crop

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminium. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These influence strongly the process of photosynthesis whose rate declines sharply. Also, the leaves of the trees have an important role in the retention of the particulate matters; they are mostly affected when the wet and dry atmospheric deposition increase.

So, the correct answer is option B.

  1. eutrophication

  2. environmental pollution

  3. biomagnigication

  4. bioaccumulation

During inversion, visibility is reduced and pollutant concentration is

  1. Minimized

  2. Maximized

  3. Reduced

  4. Decreased
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Temperature inversion traps pollutants near the ground by preventing vertical mixing, which leads to a buildup and maximization of pollutant concentrations in the lower atmosphere.

For which of the following PM10 and PM2.5 Samplers are used?

  1. Food adulteration

  2. Adulterated Petrol

  3. Environment Pollution

  4. Noise Pollution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

PM10 and PM2.5 refer to particulate matter with diameters of 10 micrometers or less and 2.5 micrometers or less, respectively, which are standard metrics for measuring air pollution.

Which is not a pollutant from exhaust of motor vehicle?

  1. SO$ _2$

  2. CO

  3. Fly ash

  4. Hydrocarbon gas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fly ash is produced due to the incomplete burning or combustion of the fossil fuels. The ash contains the carbon particles or flecks which are suspended in the air. The pollutants which are released from the exhaust of the motor vehicle are particulate matter, SO$ _2$, NO$ _x$, CO, etc. 

Thus, the correct answer is option C.

Effect of pollution is first marked on

  1. Natural balance of the ecosystem

  2. Geological cycle

  3. Rainfall and climate

  4. Fauna of a place
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pollution disrupts the natural equilibrium of ecosystems, affecting the interactions between biotic and abiotic components before specific impacts on climate or fauna are observed.

Which of the following statements is true?

  1. Lichens are affected by SO$ _2$.

  2. All pollutants are not waste.

  3. Carbon monoxide is a serious pollutant.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Lichens are well-known bioindicators sensitive to SO2, CO is a toxic pollutant, and not all pollutants are waste (some are useful substances in the wrong place).

A very harmful fibrous component causing pollution and an inflicting disease of lungs in human beings is

  1. Asbestos

  2. Eichhornia roots

  3. ABS micelle

  4. Grease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Asbestos is widely used in shipbuilding, commercial product manufacturing, power plants, and construction. It causes air pollution. Asbestos fibers are easily inhaled because they are microscopic. Once inhaled, the fibers cling to the respiratory system, including the lining of the lungs and inner cavity tissue. Asbestos fibers are rigid hence they become lodged in the soft internal tissue of the respiratory system. They cannot be easily expelled or broken down by the body thus damaging the lungs. Thus the correct answer is option A.

Which human disease becomes aggravated by atmospheric pollution?

  1. Bronchitis

  2. Leucoderma

  3. Haemophilia

  4. Rheumatism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bronchitis is caused due to infection and swollening of the bronchial tubes which carries air to the lungs. It is of two types i.e., acute and chronic. The acute is of mild type and caused by virus, even by bacteria and also exposure to substances that irritate the lungs, such as tobacco smoke, dust, fumes, vapors, and air pollution.

So, the correct answer is option A.
